Low Voltage

Threshold
(Optional)
The LVD Fuse board furnished with List 3 provides both
controller power fusing and the low-voltage battery
disconnect/reconnect function. The latter is an optional feature.
If the plant is not equipped with a LVD contactor as part of the
plant distribution, the disconnect feature of the LVD/Fuse board
is not relevant. If the plant is equipped with low voltage
disconnect/reconnect, the disconnect voltage threshold must be
selected by placing jumpers J505.1 and J505.2 across pins 1 and
2 for 42.5 ± 0.5 volts or pins 2 and 3 for 40.5 ± 0.5 volts.
